Technical field:
The utility model relates to the lighting product technical field, refers in particular to a kind of some electronic components LED lamp holder in service life that improves in the drive circuit.
Background technology:
Along with the development of LED technology, and the phototranstormation efficiency height is arranged based on the LED light fixture, energy-conserving and environment-protective, volume is little, and the life-span is long, the advantage that colour developing is good, the LED bulb has progressively entered people's life.
Present LED globe lamp comprises: lamp holder and lamp housing constitute, and not only as the joint that is electrically connected with lamp socket, it also has heat radiation function to lamp holder simultaneously.Usually lamp holder adopts metal material to make, to improve radiating effect.The LED light emitting source adopts one or more groups led chip usually, and the LED light emitting source is connected with a circuit board.This circuit board is as the drive circuit of LED light emitting source.During installation, circuit board is fixed on the lamp holder, the LED light emitting source is connected with circuit board, and by lamp housing the LED light emitting source is covered with.When LED begin luminous after, light printing opacity lamp housing is transmitted to the outside, forms the light fixture of showing up.
There are some problems in above-mentioned LED lamp, because in the inner space that circuit board is installed in lamp holder usually to be constituted, the heat of LED lamp is comparatively concentrated simultaneously, heat is difficult for being delivered to the external world, so cause the temperature in this lamp holder very high.Simultaneously, some element on the circuit board when work to also can producing higher temperature, and if these elements for a long time in the higher space of temperature, work, may cause reduce service life, very easily aging, damage.For example, the electric capacity on the circuit board, if it is in the high-temperature work environment for a long time, capacitance pole burns out easily.So,, become the direction that manufacturer need break through as guaranteeing that the operation element on the circuit board can operate as normal.
Another aspect, because in the present LED lamp, usually all electronic components all are integrated on the circuit board, so just cause the area of circuit board bigger, the space that is used to place circuit board in the lamp holder must have enough spaces and place circuit board, will cause the volume of lamp holder to increase like this.
The utility model content:
Technical problem to be solved in the utility model is exactly in order to overcome the deficiency that present product exists, and provides a kind of and can effectively improve the LED lamp holder in service life of operation element in the circuit.The utility model not only can improve the service life of some operation element in the circuit, and it can reduce the area of circuit board, optimization LED lamp holder internal structure.
For solveing the technical problem, the utility model has adopted following technical scheme: this LED lamp holder comprises: lamp holder and be arranged in the lamp holder, be used for the drive circuit that is connected with the LED light emitting source, form a ccontaining cavity in the bulb socket that is used in the described lamp holder being connected with outside lamp socket; Drive circuit comprises: main circuit board placed apart and interconnective and circuit are to the components and parts of high temp. sensitive, and wherein circuit is positioned at the ccontaining cavity of bulb socket to the components and parts of high temp. sensitive.
Described lamp holder comprise bulb socket and with the fixing housing of bulb socket, wherein circuit is positioned at the ccontaining cavity of bulb socket to the components and parts of high temp. sensitive, main circuit board is positioned at the lamp body space that housing constitutes.
Be provided with dividing plate between the ccontaining cavity of described bulb socket and the lamp body space of housing, circuit separated the components and parts and the main circuit board of high temp. sensitive by dividing plate.
Described circuit to the components and parts of high temp. sensitive by wire bonds on main circuit board.
Described circuit can be elements such as electric capacity, transistor to the components and parts of high temp. sensitive.
After the utility model adopts technique scheme, its drive circuit with the LED light emitting source is separated into two parts: circuit is to the components and parts and the main circuit board of high temp. sensitive, wherein circuit places in the accommodation space of lamp holder one end the components and parts of high temp. sensitive, and main circuit board is placed in the lamp body space of lamp holder.Circuit just is isolated in the space of a relative closure the components and parts of high temp. sensitive like this.Heat in the lamp body space also can reduce greatly to the influence to the components and parts of high temp. sensitive in the circuit, and circuit just is improved to the working environment of the components and parts of high temp. sensitive.Simultaneously, in the drive circuit circuit is separated the components and parts of high temp. sensitive, so just can be reduced the board area of led drive circuit, reduce the space that it occupies, rational in infrastructure, be applicable to all LED lamp holders.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
See shown in Figure 1ly, the utility model is a kind of LED lamp holder.In the present embodiment, lamp holder 1 mainly is made of two parts: bulb socket 11 and housing 12.Wherein, bulb socket 11 is used for being connected with lamp socket, generally as power connection of the present utility model, is equivalent to the interface in the conventional bulb.Simultaneously, lamp holder 1 is also as heat dissipation element, with heat to external radiation.In the present embodiment, be formed with an accommodation space 110 that is used for ccontaining circuit to the components and parts 3 of high temp. sensitive in the centre of lamp holder 1.
Drive circuit comprises in the present embodiment: main circuit board 2 placed apart and interconnective and above-mentioned circuit are to the components and parts 3 of high temp. sensitive, and wherein circuit is positioned at the ccontaining cavity 110 of bulb socket 11 to the components and parts 3 of high temp. sensitive.Main circuit board 2 is positioned at the lamp body space 120 that housing constitutes.
Be provided with dividing plate 13 between the ccontaining cavity 110 of described bulb socket 11 and the lamp body space 120 of housing 12, circuit separated the components and parts 3 and the main circuit board 2 of high temp. sensitive by dividing plate 13.
Circuit to the components and parts 3 of high temp. sensitive by wire bonds on main circuit board 2.Like this, circuit just is isolated in two relatively independent spaces the components and parts 3 and the main circuit board 2 of high temp. sensitive, 110 influences will weaken and the heat that forms when lamp holder is worked in the lamp body space 120 is to accommodation space, and the circuit that is positioned at accommodation space 110 will be lower than the temperature in lamp body space 120 to the temperature of components and parts 3 working environments of high temp. sensitive.So just can guarantee that circuit improves to the working environment of the components and parts 3 of high temp. sensitive, increase service life.Simultaneously, in the drive circuit circuit is separated the components and parts of high temp. sensitive, so just can be reduced the board area of led drive circuit, reduce the space that it occupies, rational in infrastructure, be applicable to all LED lamp holders.
